Magical Effects of Psychedelics Can Transform Psychiatry

Imagine a medicine that could help people process disturbing memories, sparking behavioral changes rather than merely burying and suppressing symptoms and trauma. For the millions suffering with post-traumatic stress disorder (PTSD) and depression, such remedies for their daily struggles could be on the horizon. Psychiatry is rapidly heading towards a new frontier – and it's all thanks to psychedelics, The Guardian reported.

In an advanced phase trial published in Nature in May, patients in the US, Israel and Canada who received doses of the psychedelic stimulant Ecstasy (MDMA), alongside care from a therapist, were more than twice as likely as the placebo group to no longer have PTSD - for which there is currently no effective treatment - months later.

The researchers concluded that the findings, which reflected those of six earlier-stage trials, cemented the treatment as a startlingly successful potential breakthrough therapy. There are now hopes that MDMA therapy could receive approval for certain treatments from US regulators by 2023, or perhaps even earlier – with psilocybin, the active ingredient of magic mushrooms, not far behind in the process. A small study at Johns Hopkins University, published last year, suggested it could be four times more effective than traditional antidepressants.

You could say interest in psychedelics is mushrooming. Last month, in a first for psychedelics since the war on drugs was launched in the 1970s, US federal funding was granted for a psilocybin study to treat tobacco addiction following pressure by lawmakers, including Alexandria Ocasio-Cortez.

This marks a jaw-dropping turnaround for hallucinogenic drugs. Even 10 years ago, they were effectively taboo in many academic fields and halls of power. But as the intellectual rationale behind the war on drugs has become increasingly untenable, hundreds of millions of dollars have been pumped into psychedelic pharmaceutical research.



Climate Change Causing More Change in Rainfall, Fiercer Typhoons, Scientists Say

Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms.

Taiwan, the Philippines and then China were lashed by the year's most powerful typhoon this week, with schools, businesses and financial markets shut as wind speeds surged up to 227 kph (141 mph). On China's eastern coast, hundreds of thousands of people were evacuated ahead of landfall on Thursday.

Stronger tropical storms are part of a wider phenomenon of weather extremes driven by higher temperatures, scientists say.

Researchers led by Zhang Wenxia at the China Academy of Sciences studied historical meteorological data and found about 75% of the world's land area had seen a rise in "precipitation variability" or wider swings between wet and dry weather.

Warming temperatures have enhanced the ability of the atmosphere to hold moisture, which is causing wider fluctuations in rainfall, the researchers said in a paper published by the Science journal.

"(Variability) has increased in most places, including Australia, which means rainier rain periods and drier dry periods," said Steven Sherwood, a scientist at the Climate Change Research Center at the University of New South Wales, who was not involved in the study.

"This is going to increase as global warming continues, enhancing the chances of droughts and/or floods."

FEWER, BUT MORE INTENSE, STORMS

Scientists believe that climate change is also reshaping the behavior of tropical storms, including typhoons, making them less frequent but more powerful.

"I believe higher water vapor in the atmosphere is the ultimate cause of all of these tendencies toward more extreme hydrologic phenomena," Sherwood told Reuters.

Typhoon Gaemi, which first made landfall in Taiwan on Wednesday, was the strongest to hit the island in eight years.

While it is difficult to attribute individual weather events to climate change, models predict that global warming makes typhoons stronger, said Sachie Kanada, a researcher at Japan's Nagoya University.

"In general, warmer sea surface temperature is a favorable condition for tropical cyclone development," she said.

In its "blue paper" on climate change published this month, China said the number of typhoons in the Northwest Pacific and South China Sea had declined significantly since the 1990s, but they were getting stronger.

Taiwan also said in its climate change report published in May that climate change was likely to reduce the overall number of typhoons in the region while making each one more intense.

The decrease in the number of typhoons is due to the uneven pattern of ocean warming, with temperatures rising faster in the western Pacific than the east, said Feng Xiangbo, a tropical cyclone research scientist at the University of Reading.

Water vapor capacity in the lower atmosphere is expected to rise by 7% for each 1 degree Celsius increase in temperatures, with tropical cyclone rainfall in the United States surging by as much as 40% for each single degree rise, he said.
